Hi -- I work on the fraud team at Stripe. Last October we introduced Stripe Radar ( https://stripe.com/radar ) a suite of integrated tools to help you beat fraud. While different businesses see different patterns of fraud, we believe that overall our fraud prevention is now as good or better than essentially every other product in the industry. This partly follows from Stripe’s scale: whenever a card is used, there’s now an 80+% chance that we’ve seen it before. We use this data from the global Stripe network to detect and prevent fraud with ML models that we’re constantly updating and refining.

We’d love to hear what would make us work better for you. My email is brahn at stripe.com.
